Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 6 - 8; Espinas anales: 0; Radios blandos anales: 33 - 43. Body somewhat elongated with short predorsal length (25.2-29.2% SL); a long caudal peduncle (17.2-21.8% SL); short head length (16.1-20.1% SL); and, short mandibular barbels (length 11.7-42.2% HL). Swim bladder 3-chambered, extending to above anal-fin base (Ref. 46915). Dorsum dark blue to blue-black; 3-4 lowermost principal caudal rays white; vomerine teeth appearing as 2 joined patches in juveniles (Ref. 12693); vomerine teeth united into quadrangular patch, 1.5 times broader than long, not confluent with palatine teeth patch; anal fin base elongate, its length 3.1-3.6 times in SL; dorsal and pectoral fin spines slender; snout blunt (Ref. 43281).
Body shape (shape guide): elongated; Cross section: circular.
Facultative air-breathing (Ref. 126274); Found in lakes and rivers (Ref. 56749). Adults occur in estuaries and lower reaches but has also been observed in the upper reaches during the rainy season. Species is omnivorous with a tendency to opportunism (Ref. 46915).
